Displ oblique fx shaft of r fibula, 7thN

This code describes a specific type of fracture involving the shaft of the right fibula, where the break is angled (oblique) and the bone fragments are not properly aligned (displaced). Importantly, this is an open fracture (skin broken, exposing bone) of a severe type (IIIA, IIIB, or IIIC) that has failed to heal after previous treatment, leading to a nonunion.

Use this code for follow-up encounters when a patient presents with a previously treated, displaced oblique fracture of the right fibula shaft that was initially an open fracture (type IIIA, IIIB, or IIIC), and imaging or clinical assessment confirms that the bone has not healed (nonunion). This applies when the patient is receiving ongoing care for this specific complication.

• Ensure documentation clearly specifies "nonunion" and the open fracture type (IIIA, IIIB, or IIIC).
• Verify the fracture is of the right fibula shaft and is displaced and oblique.
• This code is for subsequent encounters; an initial encounter would use a different code.
